CVE-2022-49680

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

ARM: exynos: Fix refcount leak in exynos_map_pmu

of_find_matching_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak. of_node_put() checks null pointer.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
